Trusted roof replacement in O'Fallon, IL. Our certified crews deliver precision workmanship and guaranteed results.
Our O'Fallon roof replacement process is thorough: strip existing roofing to deck, inspect and repair substrate, verify structural integrity, apply closed-cell SPF to engineered thickness, and finish with UV-protective coating. Every step documented. Every system warranted.
The buildings and homes of O'Fallon, IL face unique challenges — from seasonal temperature extremes to storm exposure — that demand roofing and insulation systems built for performance, not just price. Lapolla Industries delivers roof replacement solutions using closed-cell spray polyurethane foam that outperforms conventional materials in every measurable category.
Our O'Fallon customers see the difference in their energy bills, their comfort levels, and the longevity of their roofing systems. Spray foam does not degrade like fiberglass, does not develop seam failures like TPO, and does not crack like built-up roofing. It is a permanent solution — and Lapolla Industries is the permanent partner O'Fallon property owners rely on to deliver it right.
From inspection to completion, here is how we deliver professional roof replacement results.
Every project begins with a thorough inspection of your property. We evaluate the existing condition, identify problem areas, and use infrared moisture scanning when needed to reveal hidden issues. You receive a detailed report with photos and honest recommendations.
Our preparation process includes substrate inspection, cleaning, moisture testing, and priming. We mask all areas not receiving foam, set up containment where needed, and verify that temperature and humidity conditions are within specification for application.
Using precision spray equipment, our crews apply the foam in controlled passes to achieve the specified thickness and density. The closed-cell foam expands 30 to 40 times its liquid volume, conforming to every detail of the surface and creating a seamless monolithic barrier.
After the foam cures, we apply a UV-protective coating — silicone, acrylic, or elastomeric — selected for your specific application and climate. We then remove all masking, clean up the work area, and conduct a final walkthrough with you to verify satisfaction.

Real feedback from property owners who trusted Lapolla Industries with their spray foam projects.
"Scheduled a roof inspection before purchasing a commercial property. Their report was incredibly detailed — infrared moisture scans, core samples, photos of every deficiency. It saved us from buying a building with a failing roof."
"We needed our concrete roof deck waterproofed before installing new equipment on it. The crew applied a monolithic membrane that handles foot traffic and ponding water. Two years in and zero issues. Money well spent."
"Had spray foam applied to our flat commercial roof and the difference is night and day. No more ponding water, energy bills dropped noticeably, and the seamless membrane means zero leak points. Should have done this years ago."
